To all whom it may concern:

Be it lmown that I, HERBERT RENNO OL- coTT, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Culvert- Joints, of which the following is the specification.

This invention relates to a method and apparatus for uniting two sections of metallic or other piping, and particularly to a method and apparatus for uniting two sections of metallic culvert, in an economical, rigid, strong and secure fashion.

It is an object of the invention to provide a joint for uniting two culvert or other sections, which is simple, economical, easy to operate and easy to attach, serving to rigidly unite the two sections when attached.

Other objects and advantages of the invention will appear as the description to follow proceeds.

In the drawings:

Figure l is an elevation of two culvert sections, butt-ended in position for the attachment of the joint.

Fig. 2 is an elevation partly broken out showing the joint in process of attachment.

Fig. 3 is a similar view, illustrating the process of attachment.

Fig. 1 is a similar view illustrating the joint attached.

Fig. 5 is a perspective View of the joint.

In the drawings: 1 represents a corrugated culvert section of familiar form. The jolnt of my invention comprlses a corrugated split-ring 2 which is longer than the circumference of either culvert section and which is provided with fastening straps 3- seated in the troughs of adjoining corrugations and projecting beyondthe adjacent end of the split-ring 2. Upon the opposite end of the split-ring 2 I provide a bar lfastened, as by rivets 5, to the crests of adjoining corrugations. In attaching the device, the culvert sections are butt-ended, as indicated in Fig. 1. The split-ring 2 is moved endwise along one of them, being opened 'sufliciently to permit this, and is seated as shown in Fig. 2 with its "corrugations interlocked} upon the culvert sections 1, and the straps 3 lying in adjoining troughs and passmg Specification of Letters Patent.

' under the bar 4. Thereafter, a chain, such as 5, is placed about the joint and twisted by a bar, such as 6, to tighten the joint about the culvert sections. After the chain has been tightened sufliciently to securely lock the joint in position upon the culvert sections, the straps 8 are bent over, as shown at 6 (Fig. 4) to lock'the joint, and the two culvert sections will be found to be engaged in an absolutely rigid and secure fashion. It is, of course, obvious that other means besides the bar and chain might be used to tighten the joint, for instance, a peavey. Any adequate means for achieving this ten- Patented May 22, 1917.

sion being equally within the scope of the invention.

Having now described my invention I claim:

1 A culvert comprising a pair of full cyllndrical culvert sections arranged end to end and a joint comprising a strip corrugated throughout its length surrounding the adj acentends of the sections and overlapped upon ltself whereby said overlapped portions form a substantially watertight joint,

and means to maintain said joint 1n gripcorrugated ring havinga bar substantially removed from one circumferential end and secured to the ring, a malleable strip secured upon the other circumferential end, said ring being clamped upon said butt-ended adja cent culvert ends and secured by said malleable strip and bar.

In witness whereof, I hereunto subscribe my name to this specification in the presence of two witnesses.

HERBERT RENNo'oLooTT.
